Hottest of 'ultra-hot' planets is so hot its air contains vaporised metal:
Kevin Heng, a professor at the University of Bern, and co-author of the latest work, said: “The temperatures are so insane that even though it is a planet it has the atmosphere of a star.”
“The main lesson that exoplanets are teaching us is that we can’t just look in the solar system.” “There are really weird things out there.”

From the paper abstract:
With an equilibrium temperature of about 4,050 kelvin, the exoplanet KELT-9b (also known as HD 195689b) is an archetype of the class of ultrahot Jupiters that straddle the transition between stars and gas-giant exoplanets and are therefore useful for studying atmospheric chemistry. At these high temperatures, iron and several other transition metals are not sequestered in molecules or cloud particles and exist solely in their atomic forms.
